A soft brake pedal in your Sprinter van usually points to air and leaks or worn parts. In that situation, you should search for Sprinter van brake repair services in San Jose, CA. They have professional tools to fix it promptly before it can cause a major issue. That spongy feeling is a warning sign because your van needs firm hydraulic pressure to stop safely.
What Does a Soft Brake Pedal Mean in a Sprinter Van?
If the brake pedal is soft, then you have to press down harder than usual for the brakes to engage. Your Sprinter has a hydraulic system that provides a flow of brake fluid from your foot to each wheel. Liquids can not contract, therefore the pedal power is directly transmitted to the calipers and the brake pads. If air, water, or a leak enters this system, some of your power in the pedals is lost. This lost power is what you feel when stopping at the stop sign or traffic lights, and is what gives a vehicle a spongy feeling.
Most Common Causes of a Soft Brake Pedal
Your soft brake pedals have four problems, each of which affects how well you stop.
Air in the Brake Lines
Air in brake lines is the most frequent cause of any van having a spongy pedal. The air bubbles collapse when you step on the pedal and reduce the force that is applied to the brake calipers. It is common for air to get into the lines while performing the brake operations, and your anti-lock brake system may require a scan tool bleed.
Old or Moisture-Filled Brake Fluid
Over time, the brake fluid can absorb water from the air, reducing the boiling point of the fluid. Changing from a high to a low gear ratio on a long downhill stretch can cause weak fluid to boil and can cause vapor holes in the lines. Numerous van manufacturers recommend changing the brake fluid every two years to ensure that the pedal is firm.
Leaking or Swollen Brake Lines
A leak in the brake fluid can reduce the pressure inside the brake system and causes the pedal to sink toward the floor. Typical causes of leaking include rusted steel lines as well as cracked rubber hoses and worn caliper seals. Rubber hoses can also bulge when they are under pressure, even if there is no leak, absorbing more pedal power.
A Failing Master Cylinder
All four wheel brakes are supplied by the master cylinder which converts your foot pedal push into hydraulic pressure. Worn internal seals allow fluid to leak around the piston and the pedal will drop when the pedal is held. There is no external leak evident in this problem and a mechanic checks the pressure to ensure that it failed.
Can Engine Problems Change How Your Brakes Feel?
Engine issues may cause brake feel to become different – typically not soft, but hard. A vacuum pump, powered by the diesel engine, is used to assist the brake booster at all stops of the Diesel Sprinter. A failing pump often points to Sprinter van diesel engine repair rather than a simple brake fix. This helps you to come up with clear descriptions when you book any service for Sprinter van engine repair or brake repair.
Why Does San Jose Driving Wear Down Sprinter Brakes Faster?
The city of San Jose sees faster wear on its Sprinter brakes due to heavy stop-and-go driving and terrain. Heats pads, rotors and brake fluid dozens of times a day doing his deliveries. Rough and steep roads in the eastern foothills are additional sources of heat if you’re hauling a heavy load downhill. For fleets, a commercial Sprinter van repair plan should incorporate shorter time between brake checks. The Sprinter van repair services in San Jose, CA system can detect this wear because they are familiar with the roads in the area.
When Should You Get a Brake Inspection?
If you notice that your brake pedal doesn’t feel the same as it does before, schedule a brake inspection as soon as possible. If you see any of these warning signs, book a local Sprinter van brake inspection today:
- While applying steady pressure at a red light, your foot gradually approaches the ground.
- Your brake warning light is still on, or the fluid level is dropping between fluid top-offs.
- The parking brake does not hold when on a slope, requiring Sprinter van emergency brake repair.
What Happens During a Professional Brake Repair?
A professional brake repair begins with a comprehensive check of the fluid, lines and hoses, as well as pads and rotors. Experienced mechanics for Sprinter van repairs use a test strip or electronic testing device to test fluid moisture levels. Once the cause is determined, they change out and replace any failed parts and bleed the system until the pedal is firm. Taking your Sprinter for his final road test proves that he comes to a normal stop in normal load. Check with your shop to see the old parts to determine exactly what broke.
Conclusion
If your brake pedal is soft in your Sprinter van, the problem is either air, old fluid, a leak or a problem with the master cylinder. Every problem decreases your brakes’ hydraulic pressure, increasing stopping distances over time. Each day you are saving yourself, your load and other drivers using the busy streets of San Jose. Routine maintenance of the fluid and regular inspection will ensure that these minor problems don’t become big maintenance expenses in the future.
